Senior Agent = Senator Kenneth Taylor ??

Ken Camroux (Senator Taylor) portrayed the Senior Agent in The X-Files who with CSM was present when Section Chief Blevins assigned Agent Scully to the X-Files - in the pilot, no less.He reappeared in several episodes as, presumably, the same nameless character.

It could be the same character now named Kenneth Taylor, given his apparent familiarity with the X-Files.
